We are using a point to point link sending data in udp mode. We are finding that packets are randomly not getting through.
It is sending 66 packets a second.
It is as though it uses just enough power to send almost all the packets, but not quite all of them. If we put the 2 modules close together, all the packets get through. Further away, it drops some, and it seems that increasing the distance does not make much difference - it increases the power to get most of them through, but not quite enough.

Is there a way to force the module to maintain a higher power transmission ?
